That's the version with lifetime support, of course you could just get the version that comes with one year of support instead, which is far cheaper. Then after a year you can always decide if you really want to renew the license e.g. because you need an important bugfix that's only available in a later version. Chances are that you won't need Crossover anymore in 8 years (at least not for the reason of this thread here) when the lifetime license becomes cheaper.
